I saw an older guy today, and it looked like he had something on his head, like I don't know a dark piece of lint caught in his hair or something. On closer discrete inspection, I realized it was in his ear. Then I noticed something dark in his other ear too. I figured they must be hearing aids, but they still kept catching my eye because they were an odd color.

Then I realized: it was ear hair. All of his hair was gray/white/missing, but apparently his ear hair is still its natural color. Dark. Little tufts of dark hair in the middle of each ear....
